MCU model selection for charging point system design

Design of charging pile system MCU Model selection

It is not called hardware design , Because MCU Model selection involves more than hardware , Also about software design .

1. Selection direction

The first choice is available , It works , In particular, we should pay attention to whether there are reliable and stable channels to obtain MCU resources , The second is low cost .

MCU Abroad have NXP,ST Mainly , All models meet the requirements

There are GD MCU, Neusoft MCU , These are made in China MCU Both ARM nucleus MCU

Taiwan has new ponds MCU

2.CPU demand

MCU CPU Nuclear type and CPU digit

choice ARM nucleus , current ARM nucleus basic 32bit, Software design is universal .

3. Peripheral requirements

List one by one

UART Number , Whether idle interrupt support is required , If you need DMA

SPI Number , Lord or slave , If you need DMA

The above situation requires hardware , Software , Supply chains work together ...

I'm not going to list one by one , Only ideas

Well, based on the above ,

If the company has ST resources ,STM32F103 that will do

Provide ideas

Well, based on the above ,
